Assessment of oculomotor function after concussion
This study enrolls patients of UBMD Orthopedics and Sports Medicine who have recently had a concussion. The purpose of this study use eye tracking software to find out if eye movement is connected to recovery time from concussions. Our goal is to find better ways to diagnose concussions and understand how severe they are.
You will be in this study for about 1 hour at your first clinic visit and 1 hour at your final visit. At your first visit, we will check your eye’s response to light by shining a light into your eyes briefly. Then we will record the movement of your eyes while do tasks like reading and watching a video. After that you will followup with your physician like usual. Once you have recovered, you will perform the eye assessments again. Study takes place at UBMD Orthopedics and Sports Medicine.
In a previous derivation study, acutely concussed adolescents (within one week of injury) and healthy controls performed the King Devick test. Healthy controls and concussed patients who recovered normally (within 3 weeks) demonstrated the typical learning effect (mean 3 4 seconds). Participants who took more than 3 weeks to recover, however, showed minimal improvement (mean 1 7 seconds. In a subsequent study (in press, Journal of Athletic Training), we validated our finding in 99 patients with acute concussions, and patients who had worse oculomotor scores took significantly longer to recovery than concussed patients who had oculomotor results within the normative ranges.
Unfortunately, we cannot be certain if worsening on the KD test is due to oculomotor impairment or decrease in cognitive processing speed, which is common after a concussion. We will to repeat this study using an eye tracking software and pupilometer to decrease the effect of participant's cognitive processing speed.
